Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, and particularly relates to a wastewater treatment device. Background Technique

[0002] The waste tire pyrolysis technology utilizes the instability of organic substances in tires. The tires are sent into a pyrolysis furnace for high-temperature heating. When heated to a certain temperature, high-molecular compounds can be pyrolyzed into low-molecular compounds. The low-molecular compounds among them are pyrolysis oil, carbon black, steel wire and combustible gas. During the tire pyrolysis process, a large amount of water is required. After the water is used, it will contain impurities generated after tire pyrolysis and become wastewater. These wastewaters cannot be directly discharged and are prone to cause pollution, so they need to be treated.

[0003] In the prior art, a large amount of wastewater is generated during the production of tires and needs to be treated. In the traditional wastewater treatment device, the wastewater is introduced into a tank body and stirred and mixed with reagents at the same time. In this technology, only simple filtration of the wastewater can be achieved, resulting in poor water treatment effect. Not only is the wastewater treatment uneven, but most of the wastewater needs secondary treatment, thus reducing the efficiency and increasing the cost. Content of the Utility Model

[0004] To achieve the above object, the utility model provides the following technical solution: A wastewater treatment device includes a base. A storage tank, a guiding tank, a reflux tank and a sedimentation tank are installed on the top of the base. A reflux block and a water guiding block are installed on one side of the sedimentation tank, and a spray box and an anti-overflow box are fixed on the top. A plurality of spray pipes communicated with the water guiding block are fixed inside the spray box, and a plurality of anti-overflow pipes communicated with the reflux block are installed inside the anti-overflow box. A combined pump is installed on the top of the guiding tank. The water suction pipe of the combined pump extends into the interior of the storage tank, and the water guide pipe is also communicated with the guiding tank. A pump body is also fixed on the top of the base. The water suction pipe of the pump body is communicated with the bottom of the guiding tank, and the water guide pipe is communicated with the water guiding block. The reflux tank and the bottom of the reflux block are communicated through a pipeline.

[0005] Further, a defoaming net located below the anti-overflow pipe is fixed at the bottom of the anti-overflow box.

[0006] Further, the anti-overflow pipe and the spray pipe are not on the same horizontal plane.

[0007] Further, the number of guiding tanks is two, and the number of combined pumps is also two. Filter cylinders I are installed on the water suction pipes of one of the two combined pumps, and a tee pipe communicated with the storage tank is installed between the two filter cylinders I.

[0008] Further, the number of the pump bodies is two, a water suction pipe of each pump body is fixed with a downcomer communicated with the bottom of the guiding tank, two filter cartridges II are installed on the downcomer, and both the two water guide pipes are communicated with the water guide block.

[0009] Further, a filter tank is installed at the top of the reflux tank, the bottom of the filter tank is communicated with the reflux tank through a pipeline, a reflux pipe is connected to the top of the filter tank, and a guiding pipe communicated with the reflux pipe is fixed between the other two water suction pipes of the combined pump.

[0010] Compared with the prior art, the technical solution of the present application has the following beneficial effects:

[0011] In the wastewater treatment device, through the cooperation of the combined pump and the three-way pipe, the wastewater in the storage tank can be evenly diverted into the guiding tank. When diverting, primary filtration is completed through the filter cartridge I. After the water is discharged through the pump body and the downcomer and filtered again through the filter cartridge II, the water source will be evenly sprayed on the sedimentation tank through the guiding of the spray pipe. When the water level reaches a certain height, it will flow out through the overflow prevention pipe and return to the reflux tank to wait for discharge. At the same time, with the cooperation of the filter pipe and the reflux pipe, the water source can be re-introduced into the guiding pipe for cyclic filtration, thereby effectively improving the filtration effect and efficiency.

Detailed Embodiments

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0018] Please refer to Figures 1-4 , a wastewater treatment device in this embodiment includes a base 1, on which a storage tank 2, a guiding tank 3, a reflux tank 4, a sedimentation tank 5 and a pump body 12 located below the guiding tank 3 are fixed. A spray box 15 and an anti-overflow box 17 attached to the spray box 15 are fixed at the mouth of the sedimentation tank 5. The width of the spray box 15 is smaller than that of the anti-overflow box 17. A plurality of spray pipes 16 are installed inside the spray box 15, and an anti-overflow pipe 18 located below the spray pipes 16 is installed inside the anti-overflow box 17. A water guiding block 20 connected to the spray pipes 16 is fixed on the right side of the sedimentation tank 5, and a reflux block 19 connected to the anti-overflow pipe 18 is also fixed on the right side. The bottom of the reflux block 19 is connected to the reflux tank 4 through a pipeline. A combined pump 6 is installed on the top of the guiding tank 3. A first filter cylinder 8 is installed on the water suction pipe in the middle of the combined pump 6. The water inlet end of the first filter cylinder 8 extends into the interior of the storage tank 2 through a pipeline, and the water guiding pipe is connected to the top of the guiding tank 3. The water suction pipe of the pump body 12 is connected to the bottom of the guiding tank 3, and the water guiding pipe is connected to the water guiding block 20.

[0019] In the above structure, wastewater can be collected and stored in the storage tank first. When the storage tank is full, the combined pump can pump the wastewater in the storage tank into the guiding tank for storage. Therefore, the wastewater will be filtered through the first filter cylinder, and then guided to the water guiding block by the pump body, and sprayed into the sedimentation tank through the spray pipes, so as to expand the spraying area and make the wastewater fully mix with the reagents in the sedimentation tank. After continuous spraying, the water level rises, and the impurities sink to the bottom in a lump, while the clear water enters the reflux block through the anti-overflow pipe, and then flows into the reflux tank along the pipeline for storage or discharge, thus improving the filtering effect and efficiency.

[0020] Among them, a water pipe 13 connected to the bottom of the guiding tank 3 is fixed on the water suction pipe of the pump body 12. The water pipe 13 is in a ring rectangle shape, and second filter cylinders 14 are installed at both the front and rear ends of the water pipe 13. When the pump body pumps the wastewater in the guiding tank away, the wastewater will be diverted through the water pipe and filtered by the two second filter cylinders, thereby reducing the load of the second filter cylinders for filtering impurities, and at the same time improving the filtering effect and service life.

[0021] In addition, a filter tank 11 is installed at the top of the reflux tank 4. The bottom of the filter tank 11 is connected to the reflux tank 11 through a pipeline. The combined pump 6 is composed of three pumps, so there are three water suction pipes. A guiding pipe 9 is connected between the left and right water suction pipes of the combined pump 11. The guiding pipe 9 is connected to the water outlet of the filter tank 11 through a pipeline. When the combined pump pumps the wastewater in the storage tank away, it will also pump the wastewater in the reflux tank through the filter tank, filter it again through the filter tank, and then enter the guiding tank, and then achieve the function of circulating filtration through the pump body.

[0022] At the same time, the number of the guiding tanks 3, the combined pumps 6, the drain pipes 13, the first filter cylinders 8, the guiding pipes 9 and the pump bodies 12 is two. The water inlet ends of the two first filter cylinders 8 are connected to the top of the storage tank 2 through a tee pipe 7. The tops of the two guiding pipes 9 are connected to the filter tank 11 through a reflux pipe 10. The reflux pipe 10 is also a tee pipe. The water guide pipes of the two pump bodies 12 are both connected to the water guide block 20. The tee pipe can distribute the wastewater in the storage tank to the two first filter cylinders for filtration, improving the filtration effect and efficiency. At the same time, the filtered wastewater will also be distributed and stored in the two guiding tanks to increase the storage capacity. Then, the two pump bodies operate simultaneously for filtration, improving the filtration effect on the basis of the upper filtration, and pouring them into the sedimentation tank for sedimentation treatment at the same time. At the same time, when refluxing, the wastewater can also be distributed to the two guiding tanks through the reflux pipe to realize the cyclic treatment of the wastewater.

[0023] Such as Figure 4 , a demisting net 21 located below the overflow prevention pipe 18 is fixed inside the overflow prevention box 17. When the water level in the sedimentation tank rises and the foam contacts the demisting net, the surface tension and friction of the demisting net will make the film of the foam thinner, and finally cause the foam to break, releasing the gas inside and achieving the elimination of the foam.

[0024] The working principle of the above embodiment is as follows:

[0025] First, the wastewater is introduced into the storage tank. Then, two combined pumps are operated. The middle suction pipe will distribute the wastewater into the guiding tank through a tee pipe and complete the first treatment of the wastewater through Filter Cartridge 1. Then, the pump body operates to pump out the wastewater in the guiding tank. The pumped wastewater will also be distributed to two Filter Cartridges 2 through the downpipe to complete the second treatment. The water guide pipe of the pump body will introduce the water into the water guide block, and the wastewater will be sprayed into the sedimentation tank through the spray pipe, so as to mix with the reagent in the sedimentation tank until the water level continuously rises. The foam removal net will eliminate the foam, and the water source will be guided to the reflux tank through the overflow prevention pipe and the reflux block to complete the third treatment. It can also discharge the wastewater out through the reflux tank. When the water level continues to rise, the water will also enter the filter tank through the pipeline for filtration to complete the fourth treatment. Through the other two suction pipes of the combined pump, the water filtered in the filter tank will be introduced into the guiding tank again, and repeating the above operations can achieve the effect of cyclic treatment. Therefore, through multi-stage filtration, the filtration effect and efficiency can be improved.
